摘要:
Corrosion inhibiting compositions for ferrous and non-ferrous metal surfaces comprise one or more crystalline polyphosphates, e.g. a strontium tripolyphosphate. The compositions have particular application in the preparation of corrosion inhibiting paint compositions. A method of preparation of the polyphosphate materials is described.

A remnant soap melting and shaping assembly includes a housing including a bottom wall, a top wall and a perimeter wall attached to and extending between the top and bottom walls. The perimeter wall have a break therein dividing the housing into a base including the bottom wall and a cover including the top wall. The cover is movable between an open position and a closed position with respect to the base. A heating element is positioned within the housing adjacent to the bottom wall. A container is removably positioned in the housing and is positionable on the heating element. The heating element heats the container and melt soap positioned in the container. An inner lid is attached to an inside surface of the cover and has a perimeter edge that is mated with an upper edge of the container when the cover is placed in the closed position.

The freeze casting process for preparing a green shaped article such as a biocompatible bioceramic prosthesis or implant, comprises: a) providing a substrate at an initial predetermined spacing from one or more liquid dispensing outlets; b) writing a predetermined amount of a liquid formulation from at least one of the outlets onto the substrate, the formulation comprising: 8 to 99.99% by weight of a liquid sol comprising a liquid carrier and from 5 to 50% by weight, based on the weight of the carrier, of colloidally dispersed nanoparticles having a mean particle size in the range 0.25 to 100 nm; 92 to 0% by weight of a mineral powder having a mean particle size greater than 0.1 micron, and 0.01 to 10% by weight of at least one surfactant, freezing point depressant and/or rheology modifier; c) cooling the liquid formulation on the substrate so as to at least partially freeze the carrier on the cooled substrate; d) increasing the spacing between the one or more dispensing outlets and substrate to a further predetermined spacing; e) writing a further predetermined amount of the liquid formulation from at least one of the outlets either on to the substrate or on to deposit formed in steps b) and c) f) cooling the liquid formulation so as to at least partially freeze the liquid carrier on the substrate and/or on the deposit; and g) optionally repeating steps (d), (e) and (f) one or more times.

This invention is directed to methods of incorporating a trigger such as boric acid, boric acid salts, sodium sulfate, or other salts, into a nonwoven web substrate for the preparation of dry nonwoven products which are redispersible when put in contact with large amounts of water or liquid. In one method, the trigger is in a dry powder form and is incorporated into the nonwoven fibers followed by treatment of the fibers with an aqueous redispersible binder, and binding and drying the web. Another method is to saturate a dry bonded nonwoven web with an aqueous solution of the trigger and then dry the saturated web. Yet another method is to apply an aqueous solution of the trigger to the web followed by applying a redispersible aqueous binder to the web and then heating and drying the web.

An earth-boring bit has a bit body that includes head sections, each having depending bit legs with a circumferentially extending outer surface, a leading side, and a trailing side. A bearing shaft depends inwardly from each of the bit legs for mounting a cutter. The bit includes a beveled surface formed at a junction of the leading side and the outer surface of each bit leg. The beveled surface is angled relative to a radial plane emenating from the axis of the bit. The angle of the beveled surface is at least 20 degrees, and extends to an inner surface of the bit leg. The bit can also have a layer of hardfacing on the leading, trailing and shirttail surfaces of the bit leg. A diversion finger of hardfacing extends circumferentially to direct cuttings.

An alkyl dimethyl benzyl ammonium saccharinate is put into solution with a water soluble alcohol, such as ethanol, and subsequently mixed with water to form a aqueous solution for the treatment of wood to protect it from attacks by fungus, insects and other pests or to waterproof the wood. Preferably this saccharinate is applied by pressure to the wood after the cells of the wood have been evacuated in a vacuum. A process for making this saccharinate water soluble is disclosed which involves dissolving the saccharinate in a water soluble alcohol and then mixing the alcohol with water at about 150° F. This aqueous solution can then be used to treat wood. The alkyl dimethyl benzyl ammonium saccharinate can be put into solution with either a myristamine oxide or lauramine oxide and then mixed with alcohol or glycol. Boric acid can be added to the solution to prevent the corrosion of nails in any wood that is treated.

The present invention is directed to an improvement in the wet tensile of a nonwoven web, whether the web is for a pre-moistened nonwoven wet wipe that is both safe to use and also flushes, disperses and finally biodegrades in appropriate environments or for a nonwoven web which requires high tensile strength when in contact with liquids. An improvement in the wet tensile of the nonwoven webs is achieved by incorporating a finite amount of poly(acrylic acid) into a polymeric binder system that is applied to the web.

A modular automated diagnostic analyzer having a fluid entry module for sample aspiration, a valve module for selecting fluids and a pump module for fluidic movement so that a biological samples does not come into contact with the valve system through which calibrants and air are introduced to the fluid path. The fluid entry module encloses an aspiration tube rotatably and slidably engaged with the analysis mechanism chassis to move to different positions for the introduction of fluids into the analysis apparatus from different types of sample containers. A wiping seal removes residues of aspirated fluids from the exterior surfaces of the aspiration tube with the residue being aspirated into the analysis apparatus for disposal. Sensor modules mounted in a sensors chamber are structured to mechanically stack and interlock and include film sensors with use life record memories and each sensor module includes a fluid tight sealed passage and a sensor element. A fluid selection valve of highly polished ceramic material allows a valve cylinder passage to be selectively connected to fluid sources. A self-contained reagent pouch housing contains calibrants including tonometered calibrants in reagent pouches wherein each pouch wall includes multiple layers of materials wherein at least one layer is a thin, flexible glass material. The walls are extended to form a filler neck sealed by heat and pressure along a sealing line below a filler line so that no bubbles are trapped in the reagent pouch.
